I, the grandson of the second emperor of the Ming Dynasty, earned 100 million taels at the beginning

Time is life on the battlefield.

As the commander in chief, look at the whole situation.

If there are loopholes and defects found, if they cannot be made up in time, it will easily lead to the collapse of the whole game.

But on a chaotic battlefield, one person's voice is limited.

No matter how loud the coach's voice is, the generals on the front line can't hear him when he shouts on the podium.

Even with drums and flags and horns, on a chaotic battlefield, it is impossible for generals to notice these all the time.

Even if someone is sent to watch it specially, the subordinates cannot quickly distinguish the order, and it is easy to make a mistake.

The commander-in-chief sent out messengers, but it would take time for the messengers to rush over.

Just in case something happens halfway, the general won't even receive the order.

Therefore, the most important ability of a commander in ancient times was to control the timing.

At the right time, give the right order, and quickly convey it to the designated generals.

A slight mistake in the middle may cause the defeat of the entire war.

However, no matter how powerful the commander is, there are times when his calculations are wrong.

This is impossible when manpower is limited.

But it's different with walkie-talkies.

If the commander-in-chief finds out where there is a loophole, the generals on the front line will know it by talking about it.

Just a blink of an eye.

In such a short period of time, even if the enemy finds a loophole, they will not be able to rush over.

With the walkie-talkie, the ability of a commander can be brought to the limit.

It can be said that Zhu Zhangui had never touched the walkie-talkie in his previous life.

But a friend of his bought it.

The other party has introduced this information to him.

According to the introduction of that friend.

The transmission power of one watt seems to be 200 meters to 800 meters in the urban area, and 500 meters to 1.5 kilometers in the open space.

According to this algorithm, the transmission power of 100 watts is about 10-20 kilometers in urban areas, and 20-40 kilometers in open areas.

Zhu Zhangui estimated that in the case of no signal influence in ancient times, this power may be amplified even more.

The distance of one watt of transmission power is conservatively estimated to be at least about 2 kilometers.

With this estimate, Zhu Zhangui's eyes widened.

The survival box gives 100 watts.

According to this algorithm, this walkie-talkie can communicate at least about 200 kilometers in the current environment.

Thinking of this, Zhu Zhangui's breathing became heavy.

Buy it no matter how much you pay.

Nothing else, even just a walkie-talkie.

Quickly click to confirm receipt.

Zhu Zhangui followed the prompts and ran to the living supplies area.

As soon as he got there, Zhu Zhangui saw the big red box at a glance.

"As expected, it's not cheap!"

Running to the box and looking at the price above, Zhu Zhangui couldn't help sniffling.

The price of the survival box is 1000 taels of silver, without any discount.

"1000 taels!"

Zhu Zhangui bought 10 without blinking.

Rich and willful.

This kind of communication method of dimensionality reduction and attack, not to mention 1000 taels, even 1 taels Zhu Zhangui would bite his teeth and buy it.

After buying the items, Zhu Zhangui took out the high-powered telescope, walkie-talkie and solar charging panel, and left the supermarket.

"Hu Yu! Hu Yu!"

As soon as he came out with his things in his arms, Zhu Zhangui yelled outside the tent.

Standing at the door, holding a knife and looking at Hu Yu around him with a cold face, when he heard Zhu Zhangui's call, he turned around and entered the tent.

"King!"

Hu Yu didn't ask anything, and seemed to take orders directly.

As Zhu Zhangui's most loyal servant, no matter what task Zhu Zhangui assigns, he will complete it unconditionally.

"I need the 20 most loyal people, the most loyal."

Hu Yu didn't speak, just saluted and turned to leave.

After a while 19 men were brought in.

In a blink of an eye, the 2th day.

Zhu Zhangui rubbed his tired eyes and looked at the 20 Hu Yu who were fiddling with the walkie-talkie with great interest.

"Have you learned everything?"

Hu Yu and the others, who were happily playing with the walkie-talkie, quickly stood up straight.

"Return to the king, I have learned it!"

"it is good!"

Zhu Zhangui nodded in satisfaction and said to Hu Yu.

"Send 5 to each of Jianghuai and Shen An. Remember to record the communication distance. If you can't get in touch, immediately confirm what's going on."

"Binoculars and loudspeakers, bring them one each!"

"Tell them this is Daming's most secret thing, they just use it, don't ask too much!"

"Obey!"

Hu Yu took the order with fists in his hands, and seeing that Zhu Zhangui was a little tired, he quickly led people out of the tent and let Zhu Zhangui rest.

Shen An, who defeated Anyun Takeda Zhixin two days ago, after a simple repair, is now leading the army to Zhoufang.

"Notify all armies to speed up, don't waste time."

"Leave the surrounding villages alone as long as they don't resist. Our goal is to take down the southwest region as soon as possible!"

Shen An, who was holding a simple map in his hand, glanced at the sky and frowned.

With the arrival of summer.

Small pumpkin here has entered the typhoon season.

The typhoon blew all day yesterday, fearing that it would affect the performance of the firearms troops, Shen An ordered a day off.

The weather was a little better today, so he immediately set off with his troops.

But I don't know if the typhoon didn't go away or came back again. At this time, another strong wind blew up.

"Legion Commander, the King has sent someone!"

Just as he was considering whether to stay for a day, an officer rushed over with five guard battalion soldiers carrying packages.

Shen An handed the map to the guards, and quickly asked the soldiers of the guard battalion.

"Does Your Highness have any orders?"

The leader of the 5 people shook his head.

"Your Majesty didn't have any orders, but let us follow you from today, and brought you some things!"

After speaking, the team leader took down the package behind him, and took out a double-barrel-shaped box and a large iron horn from it.

"this is…"

Seeing what the team leader was holding in his hand, Shen An scratched his head in doubt.

"This is a new type of telescope. This is a loudspeaker that can amplify the sound many times. Your Majesty asked his subordinates to send it to you so that you can command the troops!"

While the team leader was introducing, he turned on the telescope for a demonstration, and handed it to Shen An.

"I have a telescope!"

Reaching out to take the binoculars handed over by the team leader, Shen An also patted the binoculars on his waist.

The captain smiled.

"Captain Shen Jun, the new telescope is many times stronger than your old gadget."

Shen An smiled indifferently.

He felt that the captain was joking.

The binoculars he wears are the most sophisticated ones in the entire Ming Dynasty. He doesn't believe that there are better binoculars than his now.

Besides, how good it can be is not the same as being able to see far away.

Thinking that he raised the binoculars and placed them in his eyes according to the team leader's demonstration just now.

Good guy, looking at this, Shen An's body froze in place.

So clear.

This distance, tsk tsk tsk.

Moreover, there are some rules and regulations in the mirror, Shen An guessed in his heart that it should be used to measure the distance.

Looking at Shen An who was holding up the binoculars and kept looking left and right, the five guards and soldiers of the guard battalion showed smiles on their faces. They had personally tried this thing so powerful.

When they looked at it, they were all shocked by this new type of telescope.

The team leader chuckled and explained for Shen An.

"This is the latest type of telescope. It can theoretically see things as far as 14 miles away, but in order not to hurt the eyes, we usually observe at about seven or ten miles away."

"It has a device to adjust the distance, which is convenient for you to observe different environments."

"I believe you have seen the frames inside. According to a certain calculation method, the distance can be calculated!"

"Good stuff, good stuff!"

Shen An put down the binoculars carefully, and stroked the binoculars, just like stroking a newly married wife.

"Legion Commander, give me a look!"

The lieutenant next to him felt an itch in his heart after listening to the squad leader's explanation and the shocked look of his army commander.

Seeing that Shen An retracted the telescope, he reached out to take a look.

"Go to the other side, this is a rare thing, and it is very expensive, what if you break it!"

After knocking off the lieutenant's hand, Shen An carefully put the telescope into the box, and hung it around his neck.

The cautious look is like holding a newborn child, for fear that it will be broken with a little force.

Seeing this scene, the five soldiers of the guard battalion smiled knowingly.

I was still thinking in my heart, this little thing scared you, and it's no wonder you weren't scared to death when that baby was taken out.

After Shen An put the binoculars away, the team leader handed the loudspeaker to Shen An.

"Captain Shen Jun, this is another thing, do you want to try it!"

The telescope gave Shen An a big surprise, and he was also looking forward to this big speaker.

"Little brother, let me demonstrate it. I'm a big boss and can't handle it well. If it breaks, it will be troublesome."

The squad leader nodded, stretched out his hand to fiddle with it, and pressed a button.

Then he put the trumpet to his mouth, and shouted at the marching soldiers.
